To @ZZ/whom it may concern:

Be it known vthat I, HARVEY C. BAKER, a citizen of the United States of America, and a resident of Chicago, in the county of Cook, State'of Illinois, have invented certain new and useful Improvements in Window-Awnings, of which the following is a specification.

This inventionrelates to that class of window awnings in which a spring impelled awning roller normally maintains the awning sheet in a wound condition, and which with a manual rotation of said roller against the stress of its actuating spring permits of a descent of the awning sheet and accessories into a down or unfolded condition by gravity, to be engaged and held in such unfolded condition by an automatically operating latch mechanism. And the present improvement has for its various objects To provide a structural formation and association of the guiding parts and mechanisms of the awning sheet adapted to afford a ready and convenient detachment thereof from the window frame, and a folding together of said parts for convenient storage for further use, or during the cleaning and painting of the building front.

To provide a simple and efficient structural formation and association of the stay rod of the awning sheet and the supporting brackets of the rod adapting the same for ready detachment when desired, and at the same time afford a secure attachment of said rod in place. v

'To provide a 'simple and eiiicient structural lformation of the awning extending arms', adapting them for effective operation regardless of inequalities inthe setting of the fixed upright guide rails upon which the bearing carriage of said rails have movement, and which in addition permits of a folding of the arms into a compact compass for storage and transportation.

To provide a simple and eicient automatically operating latch mechanism adapted to securely hold the awning sheet in its lowered or unfolded condition, and capable of ready release by a further manual rotation of the awning roller in an awning low- Speccation'of Letters Patent.

Fig. 3, is a transverse sectional elevation on lineB-B, Fig. 1, with the awning sheet p shown in dotted lines in its fully spread or extended condition.

Fig. 4L, is an enlarged detail transverse sectional elevatiomshowing in full lines the automatic latching mechanism in its inactive condition during the descent of the awning sheetto its unfolded position, and in dotted lines in its st'll inactive'condition as the awning extending arm is nearing the fully unfolded position of the awning sheet shown in Fig. 1,

Fig. 5, is a companion view showing said automatic latchingA mechanism lowered to a position to effect a release from its active position in which it acts to hold the awning sheet in a properly unfolded condition.

Fig. 6, is a detail section of the same on line 6-6, Fig. 5.

Like reference numerals indicate like parts in the several views.

Referring to the drawings, 1 designates a window frame at the upper portion of which is mounted in the usual detachable manner a spring actuated roller 2 of the typein which the motor spring tends to wind up the flexible awning sheet 3, with said roller 2 provided with an rend drum or slieave'2 for a manually actuated cordv lby which the roller 2 is caused to rotate and unwind the awning sheet 3 against the tensions ofthe motor spring aforesaid', as usual in the pres-v ent class of awnings.

5 designates a holding cleat secured to the window frame and adapted to receive vand,

Vthe window frame fasten the operating cord 4 aforesaid, in position convenient for access.

6 designates the usual transverse stay rod arranged intermediate the height of the window frame l for imposing an approximately vertical condition on the upper portion of the awning sheet 3 in a spread or unfolded condition of the same. In the present improvement said stay rod 6 is mounted in a detachable manner in the window frame so as to be capable of-ready detachment when it is desired to have the awning sheet 3 spread its entire length in an oblique direction as illustrated in dotted lilies in Fig. 3, as well as during-non-use of the awning or when cleaning or painting the front of the building. To thevabove end the following structural arrangement of parts is provided.

7 designates a socket plate attached to one side of the window frame and having a socket recess for the reception of an end of the 'stay rod 6.

S designates a companion socket plate attached to the opposite side of the window frame and havinga socket recess for the reception of the other end of the stay rod 6, and in the present invention said socket recess is made of some length to permit of suflicient longitudinal movement of the stay rod 6 therein to admit of the other end of the stay rod being inserted in the socket recess of the aforesaid socket plate 7 and said rod is pushed iongiiudinallT into said recess and yieldingly maintained in proper position by a spring 9 and movable abutment disk 10 arranged in the socket recess of the socket plate 8 as shown in F ig. 1.

11 designates the. upright guide rails or rods of the awning frame, mounted in a detachable manner at the respective sides of 1 in upper and lower backet members 12 and 13 .formed with socket recesses for 'the reception of the respective ends of said. rails or roos., and in manner similar to that above described in connection with the stay rod 6, and as follows:

14 designates anabutment disk and 15 an actuating spring therefor, arranged in an enlarged upper portion of the socket recess of each upper bracket member 12 aforesaid, adapted to permit sufficient longitudinal L? movement of a guide rail 11 in said recess to admitV ofthe opposite end rail being inserted in the socket recess of the lower bracketmember 13, into which said rail end is pushed and the guide rail` yieldingly maintained in proper position by the spring and vabutment disk aforesaid.

16 designates sliding heads or bloc rs moving on the guide rails 11 aforesaid7 and providing a pivoted abutment for the swinging arm 17 by which the lower end of the awnkis as follows isaeeo ing sheet 3 is pushed out in an unfolding movement of the awning. In the present improvement one end of each awning eX- tending arm 17 is connected to the side of a sliding head 16 by a pivot pin or stud 18 disposed longitudinally of the awning structure7 and to one end of the usual stretcher rail or rod 19 at the lower end of the awning sheet 3 by pivot pinsV 20 disposed transversely of the awning structure and connecting the other of said awning extending arm 17 to a head or `block 21 pivotally mounted on an end of the stretcher rail 19 aforesaid. lVith the above described pivotal connection and arrangement of partsY the awning eX` tending arms 17 will be free to operate re# gardless of any inequality or irregularity in the setting of their guide rails l1 upon the sides of thel window frame. Y

i 22 designates a vertically depending stop pin or member preferably arranged in a moving manner ineach head or block 16 and yieldingly held in a downwardly projected position by gravity preferably aided by a spring 23 as shown in Fig. 4. v

24 `designates a Yhorizontally extending holding pin or member moving in each head or block 165 and'yieldingly held in a proj ected condition by a spring 25 as shown in Fig. 6. n. Y

26 designates a pawl or dog Vindlvidual to and pivotally mounted on an awning extend ing arm 17 adjacent to its pointof pivotal atf tachment to asliding head 16, and having a curved free end or finger 27 adapted for holding abutment against Vthe depending stop pin 22 aforesaid. In thepresent im.- provement the pawl Vor dog 26 is formed with an intermediate shoulder or odset 28 adapted in the operation of the mechanism to drop past the horizontally extending stop pin 24 and release the aforesaidV end or finger 27 of the dog or pawl26 from its holding engagement with the depending stop pin 22 aforesaid. .Y Y

29 designates an inclined or Vcam formation on the side of the dog or pawl 26 adjacent to the free end of the pin orlstud 24 land adapted in an upward movement of the i pawl or dog 26 and associated awning eX- tending varm 17, to push Vthe pin or stud 24 out of the way to permit of an unimpeded upward pivotal movement of the awning eX- tcnding arms 17 and the dog or pawl 26 car-i riedv thereon. Y

The operation of the present mechanism 11s the operator draws upon the cord 4 to effect a revolution of the roller 2 and an uuwin ding of the awning sheet 3, the sliding heads 16 and accessories descend by gravity untilV sid heads 16 rest upon the lower lunchet members 13 by which further downward movement of said heads is prevented.

Further unwinding of the awning sheet 3 admits of anoutward and downward swing of the awning extending arms 17 and in such movement of said arms, the upper curved` surface of each pawl 26 rides under the stop pin 22 of a sliding` head 16 until the free end of the dog is past said stop pin 22, when said pin descends behind the point of said dog 26 to lock the awning mechanism in the spread or extended condition shown in Fie". 3, and in such condition of parts, the horizontal stop pin 24; is beneath the dog 26 to maintain the parts in the described locked condition. v

lVhen it is desired to release the above described locked condition of the parts, the operator effects a further rotation of the roller 2 and unwinding of the awning sheet 3, which permits of a further downward swing of the awning extending arms 17 to cause the shoulder 2S of each pawl or dog 26 to move past its horizontal bearing pin 24 and permit the pawl or dog 26 to drop by gravity from its previous holding engagement with its vertical stop pin 22. rlhe operator then releases the pull on the cord 4: to permit the spring roller 2 to 'exert its normal tendency to wind up the awning sheet B into a wound condition thereon. In such upward or folding movement of the awning parts, the inclined or cam surface 29 on the side of the pawl or dog 26 is adapted to push the horizontal holding` pin 24 to one side so as not to interfere with the said upward movement of parts.

In case of a violent wind storm or other like stress upon the awning sheet 3, the tend-v ency will be to force the lower portion of said awning sheet downward against the tension of the spring roller 2, and when such storm or like stress is sufficiently strong to effect such downward movement of the awning sheet and associated parts, an automatic release of the locking mechanism will take place, inalike manner as the manually actuated release above described.
